UCC28C40: PCN

Part Number: UCC28C40

Tool/software:

Hi Team,

We found the issue on part with marking "2C40". In same design, marking "28C40" is good.

May I check with you if any PCN indicate the marking change before? Beside, in that PCN, is there anything change except for marking? How can we improve this?

Hi,

2C40 COMP pin max source current is 5.5mA - which is in its latest data sheet.

28C40 does not have this spec and based on bench check it is about 2.7mA by estimation.

Please review your design to adapt this difference. We can help to review if you provide the design.

Hi,

The 5.5mA specs addition does not have PCN.
